HOSE-HOIST.

SPECIFICATION forming part of Letters Patent N0. 351,160, dated October19, 1886.

Application filed February 27, 1886. Serial No. 193,525. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN J. BRESNAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Hose-Hoists; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

Hitherto in the use of firemens hose much difficulty has beenexperienced in hoisting hose upon the roofs of buildings, or up to otherelevations, to enable the firemen to direct the stream to advantage. Theusual method is to carry a hoisting or roof line up to the roof or otherelevation, and then to let the line down and attach it to the end of thehose, which is then drawn up by the line. The hoisting or roof line,which is one of the permanent applianees of a fire-department station,is of a sufficient length (usually from one hundred to one hundred andfifty feet) to reach the roofs of the highest buildings, and. the hose,which is to be drawn up, must also necessarily reach from the roof tothe ground. Such a length of hose is very heavy, and in hoisting it itmust necessarily be either lifted bodily up -or else drawn over thecornice of the roof. To sustain the strain which is thus put upon thehose a heavy hoistingline must be used, (usually one inch in diam'eter,)and owing to the weight of the line and hose a number of men arerequired to draw up the hose, and considerable time is necessarilyconsumed; and in dragging the hose over the cornice and in contact withthe window-sills and other projecting parts of the building it becomesworn, and hence requires to be frequently replaced.

The object of this invention is to overcome these difficulties, and tofacilitate the hoisting of hose to elevated positions.

The invention consists in the portable hoist, which is hereinafterclaimed, and illustrated in the accompanying drawings, in which Figure 1is a view of the improved hoist,

showing its application in drawing hose to the roof of a building. Fig.2 is a side view of the hoist; Fig. 3, a central vertical longitudinalsection. Fig. 4 is a top view, and Fig. 5 is a front view, of the hoist.

This hoist consists of two parallel plates or side frames, A A, eachhaving a long arm or branch, a, and a short arm or branch, b. These armsor branches to and I) extend at substantially right angles to eachother, and one of them, preferably the shorter one, is shaped to form apointed hook, B, the hook pointing in the line of the longer arm. Thegeneral shape of each plate or frame, it will be seen, is that of ahookor grapnel. The two plates or frames are connected together by means ofcross bars or rods 0 G, which extend between the plates near the ends ofthe branches a and Z). Each of these rods is shouldered near each end,as at 0, against which shoulders the inner faces of the plates or framesrest,whereby the plates are held ata fixed distance apart. The rods havescrew -threaded ends d, which extend through suitable apertures in theplates or frames, and upon them, outside of the plates, nuts 6 carescrewed to hold the plates or frames together. Extending between thetwo,,plates or frames between the two branches, and near and on eitherside of the angle formed by them, are two other rods or shafts, D D,which are preferably shouldered and screw-threaded, as in the case ofthe rods 0 O, and screwed to the plates or frames by similar nuts 0 e.rods serve as shafts, upon which are rotatively mounted twoanti-friction cylinders or rollers, E E. These cylinders or rollers areslightly less in length thanthe distance between the plates A A, so thatthey may freely rotate upon the shafts. Each cylinder or roller is alsoslightly concaved on its surface, having its greatest diameter at theends and its least diameter at the center. The cylinders or rollers aremade thus concave in order that the hose which is drawn over them may bekept at the center and away from the side plates as much as possible.The side plates, A A, extend far enough beyond the surfaces of thecylinders to furnish sufficient guides for the hose and to prevent itfrom slipping off from the cylinders, and they are flared slightlyoutward in These order to prevent the liosefrom coming in contact withtheir edges,

To one of the rods 0 Opreferably the one between the long arms a aispivotally hung a swinging bail, F, to which is permanently attached asecuring or holding line, G, of, say, fifteen or twenty feet in length.The hoist itself may also serve as a reel upon which the roof-line iswound when not in use.

In using this hoist in the case of hoisting hose upon a roof, it isplacedas shown in Fig. 1. The hoist is first carried upon the roof. andthe roof-line unwound therefrom. The hoist is then placed with the longarms upon the roof and the short hooked arms holding beneath thecornice. The securing-lineis then passed around some permanent objectupon the roof and one end of the roof-line is thrown to the ground,where it is attached to the hose. The roof-line is then drawn up overthe antifriction cylinders or rollers. hen the hoist is in position onthe roof,the cylinder or roller mounted in the short arm extends outbeyond the cornice, so that in drawing up the hose it will swing freefrom the window-sills and other projections on the roof, and thecylinder or roller mounted in the long arms being above the cornice thehose and roof-line are thereby preventedfrom coming in contact with thecornice or roof. These cylinders or rollers thus serve to protect thehose and line from wear, and also render it much easier to draw up thehose,

. so that only a few men are required to manage the hose. At the sametime a much lighter roof-line may be used, since there is so much lessstrain upon it. This decreased Weight of line, together with the absenceof the usual reel, fully counterbalances the weight of the hoist, sothat no additional burden is placed upon the firemen in the carrying ofthe hoist.

The connection of the securing-line to the hoist is important, since itinsures its constant attachment thereto, and the'line thus serves as ameans for securing the hoist in position whenever it is necessary to doso.

The use of the hoist in other positions will be obvious. When placed ona ladder for drawing hose up thereon, the hooks B B will be placed uponone round of the ladder with the long arms hanging down.

The hoist is preferably .made entirely of metal, both for the sake ofstrength and to render it indestructible by fire. Two cylinders orrollers are used, since each may thereby be comparatively small, and thetwo may include a large enough radius to carry the hose clear beyond thecornice on both sides.

This hoist maybe used equally well forhoisting other things besideshose, and will be found convenient in hoisting the fire-ladders as wellas the hose.

I am aware that portable hose-hoistshaving side plates or frameshook-shaped to adapt them for attachment to roof-corniees, anti-frictionrollers being mounted in said side plates, over which the hose is drawn,are not new;

and I am also aware that it is not new to provide a permanenthose-conveying device to a building, in which rollers are mountedbetween projecting side plates. Itherefore make no claim to embrace orinclude such devices.

I claim as my invention--. In a hose-hoist, two plates or framesconnected together, in combination with an antifriction roller orrollers mounted between said plates, said plates or frames extendingbeyond the peripheries of said rollers, and being flared outward,substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
